[x] Cancel search: cruise controlPage 248 of 1333
Replace cruise control switch if it does not test correctly.
Main Switch (1992)
1) In each switch position, continuity should be present
between terminals No. 2 and 7 for switch illumination. See Figs. 22-
29. When switch is moved to Neutral position, continuity should be
present between terminals No. 1 and 4.
2) When switch is moved to ON position, continuity should be
present between terminals No. 1, 4 and 5. Connect battery voltage to
terminal No. 5 and ground terminal No. 4.
3) Battery voltage should then be present on terminal No. 1
when main switch is moved to On position. Replace switch if it does
not test correctly.
BRAKELIGHT/STOPLIGHT SWITCH TEST
Disconnect switch connector. When brake pedal is pressed,
continuity should be present between terminals No. 2 and 3. See
Figs. 22 -29. When brake pedal is released, continuity should be
present between terminals No. 1 and 4. Replace switch if it does not
test correctly.
IDLE SWITCH & THROTTLE POSITION SENSOR TESTS
Throttle Position Sensor (1992)
1) Disconnect sensor connector. Resistance between terminals
No. 1 and 4 should be 3500-6500 ohms. Use an analog ohmmeter to
measure resistance between terminals No. 1 and 3. See Figs. 22-29.
2) Slowly open throttle valve to wide open throttle.
Resistance should change smoothly as throttle is opened. Replace
throttle position sensor if it does not test correctly.
Idle Switch (1992)
1) Disconnect throttle position sensor connector. Continuity
should be present between terminals No. 1 and 2 with accelerator pedal
released. See Figs. 22-29. Continuity should not be present with
accelerator pedal pressed.
2) If continuity is not present with accelerator released,
loosen throttle position sensor mounting screw. Turn throttle position
sensor completely clockwise. Recheck continuity. Replace throttle
position sensor if idle switch does not test correctly.
INHIBITOR SWITCH TEST
Disconnect switch connector. Shift transaxle into Neutral and
Park positions. On 1991 models, continuity should be present between
Black/Yellow wire terminals No. 3 and 4. On 1992 models, continuity
should be present between terminals No. 7 and 12. See Figs. 22-29. On
all models, if continuity is not present, adjust inhibitor switch. If
switch is adjusted properly, replace switch.
VACUUM PUMP TEST
1992
1) Remove vacuum pump connector. Resistance should be 50-60
ohms between terminal No. 1 and terminals No. 2 and 3. See Figs. 22-
29. Ensure solenoid valve makes operating noise when battery voltage
is applied between terminal No. 1 and terminals No. 2 and 3.
2) If solenoid valve does not make noise, replace vacuum pump
assembly. Apply battery voltage to terminals No. 1 and 4, motor should
operate. Replace vacuum pump if motor does not operate.
